To all whom it may concern:

Be it known that I, AUGUsT HERM'CAN WIRZ, a citizen of the United States, resid- Ling at Moylan, in the county of Delaware and State of Pennsylvania, have invented a certain new and useful Bottle-Stopper, of which the following is anspecification;

The purpose of my invention is to elfec-' tually seal a bottle stopper opening of limited size and to keep the metallic part of the I stopper from coming in contact with the liquid in the bottle as much as possible.

A further purpose of my invention is to hold a cap within a cork or similar stopper and to compress the stopper against the cap.

A further purpose of my invention is to embrace a portion of the'cork or other stopper between the material of amp and a removable plug inserted therein.

A further purpose of my invention .is. to retain a cap upon or within a cork or other stopper by embedding an extension therean opening therein.

I have preferred to illustrate my invention by one .form thereof which I have constructed and tested and which has proved to from within'the stopper, at a distance from be simple, eliicient and inexpensive and at.

the same time well illustrates the principles involved in my invention.

Figure 1 is a side elevation of a preferred form, of my stopper with cap and plug therefor. Fig. 2 is a central vertical section through the structure shown in Fig. 1,

--in place within the bottle. Fig. 3 is a perspective view of the plug preferably used by me. Figs. 4: and 5 are a top plan View and a central vertical section respectively of the stopper used by me before the metallic cap is applied thereto.

I have applied my inventlon to a formof bottle stopper well known in its general characteristics, in that it closes the mouth of the bottle, but provides a small preferably central opening for pouring or dropping the contents slowly therefrom.

Within the bottle 1, I have shown a stopper 2 made of any suitable material preferably ordinary cork although rubber or any other material adapted to the purpose may be used. The bottle is filled before the stopper is applied. The contents of the bottle, however, are seldom requiredin any large quantities at any particular time and they are normally withdrawn through a relatively small central aperture 3.

I have aimed to pr'o V ide a ready and effective means of retaining the cap t'within the stopper and an easy, quick and effective closure of the opening by the top 5. At the same time I prevent the bottle contents from coming unduly in contact with the material of the metal top or plug.

Preferably concentric with the central opening '3, I 'slit the stopper, which for convenience I will hereinafter call the cork 2, annularly as at "6, to any suitable depth, preferably as deep as it is intended to embed a portion of the cap within the cork.- VVithin the slit I force the annular extension '4' of the cap 4:. This annular extension] may have a plain surface or it may be provided with the corrugations 7' or any similar projection that will be more firmly gripped bv the resilient material of which the stopper is made. I find that the gripping of the cork upon both sides of this annular extension at 8 and 9 holds it quite firmly so that even a short projection within the corkholds the cap 4 very firmly. I prefer to complete the slit to the depth required before inserting the cap as the material and construction of the cap do not admit of its cutting the cork to the best advantage.

. I finish the top of the cap in any suitable way as by flange 1O andprovide' an upper extension therefrom as at 11 in order that the flange, such as 12, upon the top, cogipera ating therewith, will aid in sealin'gthe 'operr-\ face of the flange 1,0.

Upon the top 5, I provide plug 13,whichfits within the opening 5 and is made enough largerthan the opening in the cork to cause compression of the annular portion of the cork at 14L lying between the extension 7 and the plug 13. This plug is ordinarily made of metal but if the bottle is to be filled with any liquid that would act irnuriously upon it, the plug maybe made ofvrubber, glass or any suitable material. I v

I prefer to make the fit Within the opening 3 sufficiently tight for the cap and plug to be heldupon. the .bottle by means of this frictional engagement. Normally, the fit of the plug 13 within the opening. 3 will necessarily have to be tight of the plug 13 enough to stop the leakage for the plug to provide effective retaining engagement for the plug and cap. The flange 12 can be made to assist in retention'ot the cap by frictional engagement withthe projection 11, if desired.

"The. cork may, of course, fit the mouth of the bottle as tightly at the start as may be desired. The insertion ofthe. extension 7 within the slit 6 will result in a'swell of the outer portion of the cork and a compression of the inner part.

When the plug 13 is forced within the opening 3, it will not only con'ipress the an nular portion of the cork, as at 13, against the inside of the extension sleeve 7, but will causi additional. friction-oi the cork against,

this extension 7. This holds the cap in position most tightly when the plug is in place,

av very desirable feature, since the bottle is not then so directly, if at all, under the care and observation of the user. When the plug is withdrawn, the cap is, however, still held firmly within the cork. I

While the cork is in place, the liquid makes contact with its lower end 15 and does not have access to the extension 7. hen

the plug is withdrawn, the material of the cense have provided a top or cover therefor. 1 pre: .fer to close the tube by closing the opening 3, since this prevents normal access of the contents of the bottle to the outer part of the tube while a cap or closure for the outer part of the tube alone would permit this access.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a' device 0f the character stated, a cap, a centrally apertured cork below the cap, a tubular member depending from the under side of the cap entering the cork and having its outer surface frict-ionally engaging the cork, a pouring spout upon the upper side of the cap in alinement with the tubular member and at its lower end of substantially the same cross sectional area as said tubular member and a straight plug closely fitting and guided by the pouring spout and entering the cork through the pouring spout and tubular member.-

2. In a device of the character stated, a cap, a centrally apertured cork below the cap, a tubular member depending from the, under side of the cap entering the cork and. having its outer surface frictionally engag: ing the-Mk, a pouring spout extending from; e

the upper side of the cap in alinement with the tubular member and at its lower end of substantially the same cross sectional area as said member but having its top contracted as a. plug guide and a. straight plug guided by the top of the pouring spout and entering the cork through the pouring spent and tubular member.
